Debian DSA-1846-1 : kvm - denial of service

medium Nessus Plugin ID 44711

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Matt T. Yourst discovered an issue in the kvm subsystem. Local users with permission to manipulate /dev/kvm can cause a denial of service (hang) by providing an invalid cr3 value to the KVM_SET_SREGS call.

Solution

Upgrade the kvm packages, and rebuild any kernel modules you have built from a kvm-source package version.

For the stable distribution (lenny), these problems have been fixed in version 72+dfsg-5~lenny2.
